Query of custom post types only shows first post

Question

I have a loop to show my custom post type of 'case_studies'. It originally showed all posts until I wanted to just show 3 specific posts. The problem is that it only shows the first post in my list of 'p=54,49,44'. What am I doing wrong?

$case_studies = new WP_Query();
                $count = 0; 
                $case_studies->query('post_type=case_studies&p=54,49,44');  
                while($case_studies->have_posts()) : $case_studies->the_post(); $count++;
                    $custom = get_post_custom($post->ID);
                    $case_studies_image_url = $custom['second_image'][0];

Answer 1

I think you need to change:

$case_studies->query('post_type=case_studies&p=54,49,44');

to

$case_studies->query_posts( array( 'post__in' => array( 54, 49, 44 ) ) );

I'd look at this page for LOTS more examples. http://codex.wordpress.org/Function_Reference/query_posts. when your there search for "Multiple Posts/Pages Handling".

Hope this helps, I'm still new to wordpress.
